SAR-by-NMR NMR-based method, in which small organic molecules that bind to proximal subsites of a protein are identified, optimized, and linked together to produce high-affinity ligands. The approach is called “SAR-by-NMR” because structure-activity relationships (SAR) are obtained from NMR [2].

The simple 1D NMR signature of the free ligand can synergize with measured potency data to rationalize positive and negative SAR trends and a medicinal chemist can The three-dimensional conformations adopted by a free ligand in solution impact bioactivity and physicochemical properties. Solution 1D NMR spectra inherently contain information on ligand conformational flexibility and three-dimensional shape, as well as the propensity of the free ligand to fully preorganize into the bioactive conformation. 1D NMR Search. 2D NMR Search.
